“My mother spent some years dying hers and I remember her six-weekly trips to the hairdresser for touch ups – it was a commitment that I never saw me having.

“I think it’s so empowering to finally see more and more women of every age embrace their grey hair, but I can understand the nervousness around it in a society that’s largely obsessed with looking young.”

Harris is one of a group of silver-haired sirens who has worked with Dove to come up with 10 new shade names designed to prove that grey isn’t just one colour, from dark ‘Chrome Your Own Way’ to silvery ‘I Am Titanium’.

“Our hair colour is dependent on how much melanin each hair strand has,” explains Daniel Lynes, Dove lead stylist.

“As we get older, the pigment cells in our hair follicles, which make melanin, gradually die.

“When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent colour — like grey, silver, or white — as it grows.”

The reason the shade of grey varies between each person is because it depends on how much melanin that person’s hair follicle has, Lynes says:

“Grey hairs occur when there is some still natural colour left in the hair. Once this colour has completely gone, the hair will turn white.”

Wherever you are on the spectrum, everyone wants their hair to look strong and healthy, and silver strands come with their own concerns, so it’s a good idea to consider how you’re looking after your crowning glory.

Here are five expert tips for how to get your grey hair looking its best…

1. Transition gradually

People can go grey hair at any age,” Lynes says. “This is mainly determined by our genes, however nutrition and health can also have a big impact.

“Caucasian hair seems to go grey earlier, however, on average most women in their 30s will start seeing a few grey hairs.”

Ready to embrace your greys? You don’t have to go cold turkey and ditch the dye over night.

“For those wanting to go natural, speak with your stylist about what works best for your hair.

“It may be adding highlights to break up the darker tones or you could go bold and cut it all off!”

2. Moisture is a must

“Silver hair can become quite dry and wiry, because it doesn’t hold moisture,” Lynes says.
